Province expanding access to COVID-19 Antivirals


The Ontario government is expanding eligibility for COVID-19 antiviral treatments and PCR testing to more high-risk individuals. 

“I am pleased that we will be able to offer more accessible antiviral treatment options to more people across Ontario,” said Dr. Kieran Moore, Ontario’s Chief Medical Officer of Health. “I ask everyone across Ontario to continue doing their part to keep their communities and loved ones safe by staying up to date on vaccinations and wearing masks.”

Effective immediately, the following higher-risk groups are eligible to be tested and assessed for antiviral treatments, such as Paxlovid, in Ontario:

– Individuals aged 18 and over who are immunocompromised (have an immune system that is weakened by a health condition or medications);

– Individuals aged 70 and over;

– Individuals aged 60 and over with fewer than three vaccine doses; and

– Individuals aged 18 and over with fewer than three vaccine doses and at least one risk ondition (e.g., a chronic medical condition)

Anyone who is eligible for an assessment is now also eligible for a PCR test at any testing centre in Ontario.

Since April 12, it should be easier for eligible individuals with a prescription to access antivirals by using the expanded list of dispensing locations, which include participating pharmacies across the province. A list of pharmacies that are dispensing Paxlovid is available at as of Wednesday, April 13. The list will be regularly updated as the list of participating pharmacies expands.

Treatment for antivirals must be started within five days of symptoms in most cases. Individuals who are part of higher risk groups and who have COVID-19 symptoms should immediately seek testing and care, by contacting their health care provider or visiting a clinical assessment centre. Individuals can contact Telehealth Ontario at 1-866-797-0000 for more information about where to find a clinical assessment centre or to determine if they are at higher risk.

Individuals can access Ontario’s antiviral screener tool to help determine if they are at higher risk and should be assessed for treatment. A positive rapid antigen test, PCR or rapid molecular test is required as part of the assessment for antiviral treatment. Rapid antigen tests remain available for pick up at no charge from over 3,000 retail locations in the province. Clinical assessment centres continue to be available to assess and test patients as well as to prescribe and dispense antivirals.

Health care providers may also determine if antiviral treatment is appropriate for patients based on individual circumstances even if they do not belong to one of the groups listed.

The oral antiviral Paxlovid, manufactured by Pfizer, was approved by Health Canada on January 17, 2022. Treatment with Paxlovid must begin within five days of symptom onset. To get assessed, individuals can visit a clinical assessment centre or contact their primary care provider. Eligible individuals will be able to book their fourth dose appointment through the COVID-19 vaccination portal or by calling the Provincial Vaccine Contact Centre at 1-833-943-3900, directly through public health units that use their own booking systems, through Indigenous-led vaccination clinics, participating pharmacies, and participating primary care settings. Booster doses are being offered to these individuals at a recommended interval of five months after receiving their last booster.

Data suggests that Moderna may provide a stronger protection for older adults eligible for fourth doses, speak with a health care provider or immunizer if you have any questions about COVID-19 vaccine products. PCR testing is available for eligible individuals at over 200 assessment centres and community labs, and at over 790 participating. pharmacies. Visit to find a testing location.
